# To use this, place script in `appname` folder inside your project (i.e. the folder that Xcode generates for you containing your source code, it's named after whatever you called the app). 
# Create folder there called `RawImages`. 
# Source icon should 1024x1024 and be called appIcon.png. If the icon changes, you can just run this again to regenerate everything.
# This script assumes that you have the default setup of an Images.xcassets file containing the AppIcon.appiconset.

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.

Installing Brew

The Mosquitto MQTT Server can be easily installed using Homebrew.  If it’s not installed on your system already, then a quick visit to the homepage will give you all you need to get going.  Homebrew is an OS X Package Manager for installing and updating non-Mac OS X utilities that are more commonly found in other variants of Linux.  To install the basic package manager run the following command.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
